Gas pressure gauge



A simple mechanical unit with a glass face and analog scale inside the unit that reads in pounds per square inch or the percentage of the remaining fuel. This design is a propane tank accessory and is placed between the tank and the regulator that indicates the current pressure within the tank. Consequently this apparatus enables the user to determine the level of fuel in the propane tank, thereby knowing beforehand the level of fuel in the propane tank.
